EASIEST WAY TO GET ONTO AERIAL HOOP!
I think there's no better way to get onto :) It's quite easy and don't requite so much strength as getting into basic sit from inverted straddle or pike :) So it's perfect for beginners!
HOLD HOOP AS HIGH AS YOU CAN! It is the most important thing here, it will help you sooo much if you will hold it high!
JUMP! Jump and catch hoop with your underknee!
Streighten your leg which was catching hoopand bring it to the front side of the hoop, raise your body with your arms so you can 'sit' :) You're almost there!!
Catch both sides of hoop with your hands. IMPORTANT: watch out for your 'delicate' plece ;) in that position :) try to not sit directly on THAT place :) just a little bit on a side ;)
Move your body to the one side so you can bring leg which is behind you to the fron :)
Sit comfortably and... YOU'RE THERE! :)
